Camera not working. - Moto G4 Questions & Answers

I installed Google assistant on my phone, and now my camera isn't working. Any thoughts on what I can do to get it going. The camera controls are on screen, but it's just black. I don't want to go back and undo the changes to the build prop to get it back, but that is my last resort. Thanks.

Camera Problem

Well I just got my JasJar and when I press the camera the app comes up and then nothing but a black screen. Is there any software update out there? The camera that is on the screen works but not the one on the back.
Jr...
I believe that you able to do an exchange...most probably your camera hardware is faulty.
having the same problem with camera. Screeen is black but video cam still works
.. any suggestions?
dont point it to the ground? ensure you are in a vary bright place! make sure you dont have the cover over it!!! adjust the settings by clicking on the tools on the bottom right and adjust ambience and settings, really get creative and perform your own manual adjustments. switch the flash on?
the camera is **** and dark, so dont expect miracles.
alternatively, send it back. it should work.
Do what Simon suggested but if that doesn't help, change the settings in Camera to Auto incase its on something else. You mentioned that video cam works but camera mode doesn't. What about the other modes like Burst, Sport etc etc?
If nothing helps, try a soft-reset. If that doesn't help, try a hard-reset. If that too doesn't help, then a ROM re-install is in order. Now, if that too doesn't help, then i'm sorry but you will need to send it to the service centre.

bugs i have noticied

So i got this beautiful machine today and ive had a few problems on it. So far the camera has messed up on me twice. I was taking a picture of someone with the rear camera and it just froze. I clicked home and then force stopped the camera application from settings and then tried to go to the camera and it said camerancouldnt connect. Had to restart. Then i took some pics and videos front facing and rear. Now when I go to the camera app it stuck on the front facing camera, no matter which camera I try to use. Also i work at Bestbuy and when. We were trying to set up the demo device we connected it to an HD screen via hdmi obviously and i tried playing a youtube video in HD. Kept saying tap to refresh so I tapped and then all of a sudden it just hard crashed. I had to just turn it back on. Also right now just trying to watch HD youtube keeps telling me to tap to refresh. Not sureif thats just me and my internet cnnnection but yeah. Just wanted to put these out there. Remember still an early version but I do not think google should have removed the beta tag on this OS

Camera App Problem

I'm having a big problem with the camera app.
It appears that when I open, the camera automatically starts and tries to take pictures (by focusing) and then going black, and then coming back up to the camera viewfinder screen, then black, then viewfinder, then black, etc forever. It's as if the camera app opens, closes, opens, closes, again and again.
Both the rear and front camera have this problem...
The camera app used to work just fine.
When I try to use Google Goggles, it lags the camera terribly, and that's when it started (after using Goggles today). I uninstalled Goggles, but the camera is still messed up.
I use the camera in other apps just fine, like the Yelp Monocle, Camcorder and Qik, and they are still working fine, even if the camera app is broken.
I have tried Clear Data from the camera app, rebooting, battery pulling. I'm on my last resort, factory reset!
can we get some info about your phone... rooted? rom? ect...
Bone stock.
well with that note i dont have a clue... the first time i turned my phone on i rooted it and never looked back!
i would power off, and volume down and power to get to h boot and factory reset...
So apparently the problem has to do with Geo-tagging, or anytime the GPS is in use with the camera in a picture taking capability.
I have turned geo-tagging off and the camera app is seeming to work...
i am glad you figured it out bro! sorry i wasnt any more help though...
just flashed the gingersense rom and omfg this is NICE, just sayin... maybe you might want to come to the DARK SIDE and root, lol

Front video not working. Want to back up app data before trying factory reset.

For some reason, the front camera gets all weird when taking a video. Back camera works fine, just not front. All the colors become muted and blue tinted, everything goes dark, and the quality drops signifgantly. Here's what I mean: imgur.com/a/t1XOc (I can't post links yet :/ so just copy paste)
First picture is what selfie (front) camera sees, 2nd is what happens when I try to take a video using the front camera, 3rd picture is what the selfie camera looks like afterwards. It gets "fixed' after i switch to front camera and back. I think it's a hardware defect, since I haven't found anyone else having problems with this on the internet.
I want to factory reset to be sure (is there a way to turn on safe mode? I can't figure out how on this phone) unfortunately I already put a bunch of games on my phone that don't have cloud save, and I don't want to loose all that progress. Is there a way I can back up all the app data without rooting? (I haven't rooted in case I needed to send it back for repairs). If I do restore the apps, will they still be able to receive updates and will I still be able to make inapp purchases?
Phone comes with weshare... Have not tried it myself.

How to set Front camera as system default because Rear camera is water Damaged

My moto g4 plus dropped in water. I dried it completly and it works flawlessly next day rear camera stopped working . I have have tried everything. Hard reset ..New applications.. custom Roms... Open board clean it all and reinstall camera hardware component but all failed. NOW I want to know is there any way to set front camera as my default back camera. It works some time by luck but don't focus. Because flash and camera works simultaneously I can't turn my flash on. When I use a third party application to turn my flash on. It just turns on for a second then again turned off. I know everything else is just working fine. So my Question is there any method to disable my back camera and set my front camera as default so that I can use flash, WhatsApp Web.. etc. I have my phone rooted on Naugat 7.1. Please also suggest hardware solution to fix my damaged camera. Thanks.
